Post by: vivekrai on February 25, 2012, 11:04:40 AM

How Do I proceed?

Diazomethane reacts with carboxylic acids to produce methyl esters. The second and third step you should know.

I was just confused that carbenes also do form three membered rings with the olefinic bond. But here the -COO's H is way too acidic to react with it.

Is it okay? Thanks, I've got rest.

Carbenes do form cyclopropanes with olefins, but diazomethane is not a carbene until you heat it or hit it with light.

Thanks for the input.
